Description

  The present invention relates to a gaming machine such as a pachinko machine.

As a conventional gaming machine such as a pachinko machine, a decorative member called a center case is provided in the gaming area on the front side of the gaming board, and the gaming board is provided through a transmission part (opening or a part that can be seen through) formed in the center case. A display device with a display unit attached to the rear faced to the front is in widespread use. For example, a so-called one-type pachinko machine includes a display device (for example, a liquid crystal display device) that can perform variable display of a plurality of symbols (identification information) called special figures in a plurality of display areas, and the front of the game board In the game area, the display unit of the display device is arranged facing the front, and a start opening is provided for winning a game ball flowing down the game area, and the game ball is awarded to the start opening. The variation display game with the variation display is executed on the condition of.
In this type of gaming machine, for example, as disclosed in Patent Document 1, a center case provided with a transmission part in the center is screwed to the front surface of the game board (that is, in the game area), and A display device with a display unit facing backward is screwed to the rear surface of the game board so that the variation display of the identification information on the display unit of the display device can be viewed from the front side of the game board.

JP 2004-180837 A

By the way, in the conventional gaming machine, when the center case and the display device are attached to the game board, it is necessary to screw them from both the front and back sides of the game board, and the workability is poor. Since the center case and the display device may be detached not only during the manufacturing process of the gaming machine but also at the time of maintenance, etc., it is particularly desired to improve the mounting workability.
In addition, since the center case and the display device are screwed separately to the game board, there is a positional shift between the transmission part of the center case and the display unit of the display device (a shift that causes a problem in terms of visibility). There was also a problem that it was relatively likely to happen.
Accordingly, an object of the present invention is to provide a gaming machine that has good workability when the center case and the display device are attached to the game board and in which the misalignment between the transmission portion of the center case and the display portion of the display device is prevented. .

The gaming machine according to claim 1 of the present application includes a center case attached to the front surface of the game board and having a transmission portion formed in the center, and a display portion attached to the rear surface of the game board via the transmission portion of the center case. In a gaming machine provided with a display device that is visible from the front,
The display device is provided with a boss extending forward,
The game board is provided with an insertion part for inserting the boss,
The center case is provided with an attachment portion in which an attachment port is formed through which a screw member for screwing the center case to the boss is inserted from the front surface.
The center case and the display device are attached to the game board so as to sandwich the game board by the screws.
Here, the “transmission part” means an opening or a part that can be seen through. The “screw member” is a fixing member having a shaft portion, and means, for example, a screw, a bolt (a member having a shaft portion on which a male screw is formed), a nail, or the like. The “boss” is a portion into which the shaft portion of the screw member enters. In addition, here, “screwing” means that the center case is inserted into the boss of the display device by inserting the shaft portion of the screw member into the boss and inserting it into the boss (for example, screwing or driving). Means fixing.

  In addition, as a preferable aspect of the present invention, for example, as described in claim 2, in a state where the center case and the display device are attached to the game board, a front end of the boss and a rear surface of the attachment portion opposed to the front end. It is good also as a structure in which a space | gap is formed in between.

Further, for example, as described in claim 3, by making the front end side of the boss thinner than the rear end side, a small diameter portion is formed on the front end side of the boss and a large diameter portion is formed on the rear end side of the boss. ,
An elastic member is disposed on the outer periphery of the small-diameter portion, and the elastic member is sandwiched between the attachment portion and the large-diameter portion in a state where the center case and the display device are attached to the game board. It is good also as a structure.

  According to the gaming machine of claim 1, the center case and the display device are completed by attaching the center case and the display device to the game board only by screwing with a screw member inserted from the front side of the game board. The mounting workability is significantly improved. Further, since the center case and the display device are directly fastened, positional deviation between the transmission part of the center case and the display unit of the display device can be prevented, and high visibility of the display unit can be realized with high reliability.

  According to the gaming machine of the second aspect, the gap between the center case and the display device can surely generate a holding force with respect to the game board, and the center case and the display device are not rattled with respect to the game board. It can be attached securely. The board portion constituting the game board is usually made of a material with unstable thickness (such as a plywood board) (those with low dimensional accuracy and large variations in the finished dimensions). Also, the holding force can be surely generated.

Further, according to the gaming machine of the third aspect, when the screw member is a screw or a bolt, the restoring force of the elastic member acts to prevent the screw member from loosening, and the center case and the display device narrow the game board. The holding force can be maintained with high reliability, and the center case and the display device can be prevented from rattling or falling off due to looseness of the screw member.
In order to prevent the screws from loosening, it is conceivable to stop them from the front with a sems screw (screw with a spring washer). Therefore, there is a risk that it may hinder the flow of game balls in front of the game board. However, according to the present invention, the elastic member for preventing loosening is configured to be stored behind the center case mounting portion (around the small diameter portion at the tip of the boss on the display device side). There is also an effect that it can be easily avoided.

Hereinafter, as an embodiment of the present invention, a configuration example when applied to a pachinko apparatus will be described with reference to the drawings.
A. Overall Configuration of Game Board FIG. 1 is a front perspective view of a game board 1 of a pachinko machine according to this embodiment. FIG. 2 is a rear perspective view of the game board 1. In FIG. 1, reference numeral 1 denotes a game board, and a game area 3 is formed by a substantially circular area on the front surface being surrounded by a guide rail 2.

As shown in FIG. 1, the game board 1 includes an out-ball inlet 4, a center case 10, a normal electric accessory type start port (start winning port) 11, a variable winning device 12, general winning ports 13 to 16, A special figure indicator 17, a special figure memory indicator 18, a number of obstacle nails (not shown), and the like are provided. The center case 10 is a member surrounding the front surface of the display unit 21 of the display device 19 (shown in FIG. 2) attached to the game board 1 from the back side. The special figure display 17 is a so-called special figure display that performs a variable display synchronized with a variable display of a special figure, which will be described later, on the display unit 21 using a 7-segment display.
As shown in FIG. 3 to be described later, a plurality of openings including a center case opening 5 for fitting the center case 10 is formed in the board (so-called veneer) constituting the game board 1 (center case). The reference numerals of the openings other than the opening 5 are omitted). Further, on the inner surface of the center case opening 5 of the game board 1, insertion portions 6 are formed at positions corresponding to the bosses 32 for inserting bosses 32 of the control base 30 described later. In this case, the insertion portion 6 is a concave portion formed on the inner peripheral surface of the center case opening 5.

The display device 19 includes a display device body 20 (for example, a liquid crystal display device) on which a display unit 21 (screen) capable of displaying identification information (sometimes referred to as a special figure) such as numbers and characters is formed (see FIG. 2). Can be displayed). For example, special charts are displayed in three vertical columns on the left, center, and right, and special figures consisting of numbers, letters, etc. in each column are displayed in a stopped state (stop display), or in a fluctuating state (for example, vertically) Display in a scrolling state) (that is, a variable display). In addition, the display unit 21 can display an image for presentation or information notification such as a background image and a character image separately from the special figure.
The variable winning device 12 is a device having a special winning opening 12a that is opened on condition that a big hit, which will be described later, is achieved.
The starting port 11 is a winning port that functions as a starting port for a special drawing as will be described later, and includes an opening / closing member 11a that changes the opening of the opening as the winning port. The start port 11 is disposed below the center portion of the center case 10.

B. Configuration of Display Device Next, the configuration of the display device 19 of this example will be described with reference to FIGS. 3 is a perspective view showing a state before a control base 30 (to be described later) is attached to the game board 1, and FIG. 5 is a longitudinal sectional view showing the screwing portions of the center case 10 and the display device 19 (A in FIG. 1). FIG.
The display device 19 has the above-described display device body 20 and a rectangular display opening 31 (shown in FIG. 3) facing the display unit 21 of the display device body 20, and is attached to the back side of the game board 1. And a control base 30.
Here, the display device main body 20 is disposed so that the display unit 21 faces the display opening 31 of the control base 30 and is fixed to the rear surface side of the control base 30 in advance.
2 is a game control device that performs control for game progression and overall control of the entire gaming machine. In this case, the game control device is attached below the display device 19 on the back surface of the game board 1. It has been.

As shown in FIG. 3, the control base 30 has bosses 32 extending forward at a plurality of locations (four locations in this case) around the display opening 31. As shown in FIG. 5, the boss 32 includes a cylindrical protrusion 33 formed of a base material (synthetic resin) constituting the control base 30 and a cylindrical metal in which the rear end side is embedded in the cylindrical protrusion 33. It is comprised by the member 34 (black coating part in FIG. 5).
Here, the cylindrical metal member 34 is a member embedded in the base material by insert molding, and a screw hole for screwing is formed on the inner surface. In addition, when using a tapping screw as a screw member, the said screw hole is naturally unnecessary.
Further, the front end side of the cylindrical metal member 34 protrudes to the front side from the cylindrical protrusion 33 and is exposed. Accordingly, the front end side of the boss 32 is thinner than the rear end side, and a small diameter portion 32 a is formed on the front end side of the boss 32, and a large diameter portion 32 b is formed on the rear end side of the boss 32.
In the attached state, the boss 32 is inserted into the insertion portion 6 of the game board 1 described above. Here, the attached state means a state in which the center case 10 and the control base 30 (that is, the display device 19) are attached to the game board 1 (the same applies hereinafter).

C. Configuration of Center Case Next, the configuration of the center case 10 of this example will be described with reference to FIGS. 1 and 4. FIG. 4 is a perspective view showing a state before the center case 10 is attached to the game board 1.
The center case 10 is attached to the front side of the game board 1, and has an opening 41 (transmission portion) that allows the display unit 21 of the display device body 20 to be viewed from the front side through the display opening 31 of the control base 30. Have in the center.

The center case 10 is a member that is attached from the front side to a board (veneer) constituting the game board 1 so as to surround the front surface of the display unit 21 of the display device body 20, and the bottom of the inner window opening 41. Are formed with a game ball rolling surface 42 (a so-called ball-showing stage) on which a game ball can roll.
An armor portion 43 that protrudes forward from the surface (game board surface) of the substrate is formed mainly on the upper side of the center case 10, and a game ball that has flowed down on the center case 10 is an upper surface of the armor portion 43. It rolls down (inclined surface) and flows down to the left or right. The armor portion 43 protrudes to a position facing the inner surface of a glass plate (not shown) covering the front surface of the game board 1 with a slight gap, and the game ball flowing down on the center case 10 is the armor portion 43. Always flow down to the left or right.

  Further, a cylindrical warp guiding portion 44 for guiding the game ball into the center case 10 is provided on the left side of the center case 10, and a warp inlet 45 is formed at the inlet, and a warp outlet 46 is formed at the outlet. Has been. For example, a game ball that has flowed down to the left after flowing down on the center case 10 hits the obstacle nail (not shown) and flows into the warp inlet 45 with a certain probability. In addition, the game ball that has flowed in this way is configured to flow down from the warp outlet 46 onto the game ball rolling surface 42. In the center case 10, a game ball that does not pass through the warp guiding portion 44 may flow and flow down onto the game ball rolling surface 42. For example, a configuration may be adopted in which a game ball that has flowed down to the left of the center case 10 hits an obstacle nail (not shown) and flows into the center case 10 with a certain probability.

The game ball rolling surface 42 has a raised shape at the center, and a guide groove 47 is formed in the middle of the center. In addition, a ball passage port 48 through which the game ball flows down below the back side of the center case 10 is formed on the back side of the guide groove 47.
Here, the guide groove 47 is inclined downward toward the back, and the game ball flowing down to the game ball rolling surface 42 flows into the guide groove 47 with a certain probability and flows to the back side. It flows into the lower back side of the center case 10 through the ball passage port 48.
Further, a start winning induction port 49 is formed at the center of the lower end of the center case 10 (a position directly above the start port 11). The game ball that has flowed into the ball passage port 48 is discharged from the start winning induction port 49 via a communication portion (not shown) and is guided to the start port 11 (that is, flows into the start port 11 with high probability). It is configured. The game balls that have flowed down to the game ball rolling surface 42 and were not guided by the guide groove 47 flow down from the front end edge of the game ball rolling surface 42, but in this case, the winning ball 11 is won. Probability is relatively low.

D. Next, the attachment structure of the center case 10 and the display device 19 to the game board 1 will be described with reference to FIGS.
As shown in FIGS. 4 and 5, a flange-like (hook-like) attachment portion 51 is formed on the outer periphery of the center case 10 so that the back surface is joined to the game board surface in the attached state. The mounting portion 51 has a plurality of mounting ports 53 corresponding to the bosses 32 through which the screw members 52 to be screwed into the bosses 32 of the control base 30 (that is, the cylindrical metal members 34) are inserted from the front surface. (In this case, 4 locations) have been established. For example, as shown in FIG. 5, the screw member 52 has a dish-shaped head (in this case, a countersunk screw), and the mounting port 53 accommodates the entire head of the screw member 52 inside. It has a shape. Thereby, it is possible to avoid a problem that the head of the screw member 52 protrudes from the game board surface and obstructs the flow of the game ball. Here, the screw member 52 of this example is a screw that is screwed into the boss 32 (that is, inside the cylindrical metal member 34).
The center case 10 and the display device 19 (the control base 30 and the display device body 20) are screwed (in this case, screwed) to the boss 32 with respect to the boss 32 as shown in FIGS. The game board 1 is attached to the game board 1 so as to hold it. In addition, holding | grip here is a game board by the contact surface (rear surface 51a of the peripheral part of the attaching part 51) with respect to the game board front surface of the center case 10, and the contact surface 35 with respect to the game board rear surface of the display apparatus 19. 1 means to sandwich a substrate constituting 1.

  As shown in FIG. 5, in the mounted state, a gap having a front-rear dimension of ΔL is formed between the front end of the boss 32 and the rear surface of the mounting portion 51 (in other words, the front surface of the game board) facing the front end. It is the composition which becomes. That is, the length L from the contact surface 35 that contacts the back surface of the game board 1 on the front surface of the control base 30 to the front end surface of the boss 32 (in this case, the front end surface of the cylindrical metal member 34) is Is set so as to be always smaller than the thickness T of the game board 1 even in consideration of a dimensional error of the thickness T of the game machine 1, and thereby a gap with a minute dimension ΔL (ΔL = T−L> 0) is formed. It is the structure formed in the attachment state.

In addition, as shown in FIG. 5, a coiled spring 36 (elastic member) is attached to the outer periphery of the small diameter portion 32a on the front end side of the boss 32, and in the attached state, the attachment portion 51 of the center case 10 and The spring 36 is sandwiched between the large diameter portions 32b of the boss 32 so as to be compressed. The spring 36 exerts an effect of preventing the screw member 52 (screw) from loosening in the same manner as the spring washer because the restoring force acts in the direction of pulling the attachment portion 51 away from the boss 32.
5 shows a state before the screw member 52 is screwed (before the center case 10 is attached), and shows a state in which the rear surface 51a of the attachment portion 51 is separated from the front surface of the board of the game board 1. However, in the mounted state, the rear surface 51 a of the mounting portion 51 comes into contact with the front surface of the board of the game board 1.

E. Outline of Game Next, an outline of a game performed in the pachinko machine of the present embodiment and a flow of the game will be described.
First, at the beginning of the game (or before the game is started), the customer is waiting (during the demonstration), and the customer waiting image (moving image or still image) is displayed on the screen (display unit 21) of the display device 19. ) Is displayed.
When a game ball that has been thrown into the game area 3 through the guide rail 2 wins the start opening 11 (that is, when there is a start win for a special figure), a special figure variation display is performed on the screen of the display device 19. Then, a variable display game is performed.

  If the stop display mode of this variable display game (a combination of special figures derived by the variable display) is a specific mode (for example, a doublet such as “3, 3, 3”), a privilege called a big hit is obtained. It is given to the player. In terms of control, for example, on the condition that there has been a start winning, the value of the big hit random number is extracted and stored, and the random number value that has been extracted and stored is compared and determined at the time of determination. Based on the determination result, whether or not to make a big hit is determined in advance, and the variable display game is started in response to this determination.

  When the big hit is made, an opening operation is performed in which the big winning opening 12a of the variable winning device 12 is temporarily opened for a period of up to ten winnings within a range not exceeding a prescribed time (for example, 30 seconds). . This release operation is performed up to 15 rounds, for example. In this jackpot state, the display of the jackpot image for producing the jackpot state or notifying the player of the number of jackpot rounds is executed on the screen of the variable display device 10.

In addition, when a game ball is further won in the start port 11 during the above-described special figure variable display game or big hit, a special figure start memory display is performed on the special figure storage display 18 and stored, for example, up to four. After the variable display game or jackpot is over, the special display variable display game is repeated or returned to the customer waiting state based on the memory (ie, the start memory).
That is, if the variable display game ends with a big hit, the game shifts to a big hit state, and if the variable display game ends with a start and there is a start memory, the variable display game is executed again, and the variable display game ends with a start and no start memory is stored. If the jackpot ends and the start memory is stored, the variable display game is executed again. If the jackpot ends and there is no start memory, the flow returns to the customer waiting state.

  According to the gaming machine of the present example described above, the mounting operation of the center case 10 and the display device 19 to the gaming board 1 is completed only by screwing with the screw member 52 inserted from the front side of the gaming board 1. The mounting workability of the center case 10 and the display device 19 is remarkably improved. Further, since the center case 10 and the display device 19 are directly fastened, it is possible to prevent the positional deviation between the transmission part (opening 41) of the center case 10 and the display unit 21 of the display device 19 and to ensure high visibility of the display unit 21. It can be realized with high performance.

  Further, by setting the gap ΔL, the holding force with respect to the game board 1 by the center case 10 and the display device 19 (control base 30) is surely generated, and the center case 10 and the display device 19 are rattled with respect to the game board 1. It can be securely installed without any problems. Note that the board portion constituting the game board 1 is usually made of a material with unstable thickness (such as a plywood board) (those with low dimensional accuracy and large variations in finished dimensions). However, the holding force can be reliably generated.

Further, the restoring force of the elastic member 36 acts to prevent the screw member 52 (screw) from loosening, and the holding force of the center case 10 and the display device 19 with respect to the game board 1 can be maintained with high reliability. It is possible to reliably prevent the center case 10 and the display device 19 from rattling or dropping off due to the looseness of the member 52.
In the conventional gaming machine, the center case or the like is directly screwed to the veneer constituting the gaming board with wood screws, and no loosening washer or the like is used. However, in general, it is conceivable to prevent screws from loosening with a Semus screw (screw with a spring washer) from the front, but with a Sems screw, the head of the screw is on the front (front of the center case attachment) ) May cause a hindrance to the flow of game balls in front of the game board. However, according to the present invention, the elastic member 52 for preventing looseness is configured to be accommodated behind the mounting portion 51 of the center case 10 (around the small diameter portion 32a at the tip of the boss 32 on the display device side). As described above, there is an effect that it is possible to easily avoid the obstacle to the flow of the game ball. Particularly in this case, since the elastic member 52 is configured as a countersunk screw and its head is housed in the mounting portion 51, it is reliably avoided that the game ball flows down.

The present invention is not limited to the above-described embodiments, and various modifications and applications are possible.
For example, the screw member 52 of the above embodiment is a screw that is screwed into the boss 32 (that is, inside the cylindrical metal member 34), but the present invention is not limited to such a mode. For example, the screw member 52 may be a member that is screwed by being press-fitted into the boss 32 (a member that is not screwed). However, if the screw is not a screw, the loosening prevention such as the elastic member 36 usually has no effect, and therefore it is necessary to provide another configuration when the loosening prevention is required.
Even when a screw is used as the screw member, a so-called through bolt may be used as the screw member of the present invention. That is, the screw shaft portion of the screw member is penetrated through the control base 30 so that the front end protrudes rearward from the rear surface of the control base 30, and a nut is screwed into the front end of the screw shaft portion from the rear surface of the game board. And may be fixed. In this case, it is not necessary to embed the metal member (cylindrical metal member 34) forming the female screw by insert molding.
Further, in the above-described embodiment, a so-called one-type pachinko machine (a game in which a variable display game is performed by a start winning prize and a big winning opening is opened when a big hit is made as a result) is taken as an example. However, as long as the present invention includes a center case or the like, the form of the game board is not particularly limited, and can be applied to other types.

  In addition, it should be considered that the embodiment disclosed this time is illustrative and not restrictive in all respects. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

It is a front side perspective view of the game board of a pachinko machine. It is a back surface side perspective view of the same game board. It is a perspective view which shows the state before attaching a control base (display apparatus) to a game board. It is a perspective view which shows the state before attaching a center case to a game board. It is a longitudinal cross-sectional view (A sectional view in FIG. 1) which shows the screwing part of a center case and a display apparatus.
